BAG.

SPECIFICATION forming part of Letters Patent No. 240,158, dated April 12, 1881, Application tiled March 14, 1881. (No model.)

To all 'whom it may concern:

Be it known that I, THOMAS H. MAYHEw, of Hyde Park, of the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Bags; and I do hereby declare the same to be described in the following specification, and representedin the accompanying drawings, of which- Figure 1 is aside view of a bag of my improved kind. Fig. 2 is a horizontal section, and Fig. 3a vertical section of it, taken through the bottom laps. Fig. 4 is a perspective representation of the bag-body inverted and slitted at opposite parts of one end preparatory to closing the bag at such end in manner as hereinafter described. Figs. 5, 6, and 7 are hereinafter referred to and described.

My improvement isintended more especially for bags which are used in oil-presses for holding a material from which oil is to be extracted by pressure, the improvement serving not only to strengthen the bag at its bottom corners, but to there facilitate the flow or discharge of oil. Bags for. the purpose described as commonly made or seamed at their lower ends are v-ery liable, when in use in an oil-press, to become clogged and to break open at the corners of their bottoms. With my improved bag, there being a single thickness of material at and above each lower corner, the oil can easier escape through such, and as the bag at bottom is closed with a twofold thickness of material, with a row of stitching at the edge of each of the laps, it becomes very much stron ger than a bag whose bottom is sewed together with a single row of stitches.

In carrying out my invention the bag-body is to be supposed to be anat tube of canvas or duck or other suitable material. It may be woven tubular, or may be made of a rectangular piece of material fastened or sewed together at its two opposite edges. Having a tube so made, it is to be slitted at two opposite parts of the end to be closed, each slit being of a length equal to half the width of the lap the cloth is to have at the closure. at a, a in Fig. 4, A being the tube of cloth in which they are made. Next, one of the two portions b c of the cloth between the slits is to be turned down into the tube in manner as shown in Fig. 5, the part so turned in being These slits are shown A folded at each end obliquely, as represented in Fig. 6, in which each of such laps or folds is shown at e as triangular, and on the outer side of the material. Next, the part c, so folded at its ends and turned down within the tube, is to be sewed or stitched or fastened along its edge to the opposite side of the tube, the stitching heilig shown at d in Fig. 5. Next, the part or lap b is to be folded at its ends in manner as shown in Fig. 6, except that the triangular portions are to be folded against the inner face of the part b. This having been done, the part b is to be turned Aover against the outer surface of the opposite side of the tube, as shown in Fig. 7. The part or lap bis next to be fastened or sewed along its outer edges to the next adjacent side of the tube. The bottoming of the bag will thus have been completed, it having a double thickness, or two folds or laps of the cloth. or material.

In some cases the bottoming may be made without having the laps folded in at their ends in manner as shown in Fig. 6; but it is pret'- erable to make it with such folds.

I claim as my invention as follows, viz:

l. The method, substantially as described, of making the bottoming of a bag, it consisting of slitting the tubular body at one end, as specified, at opposite parts thereof, and next turning into the tube one of the portions between the slits and fastening it along its edge or edges to the opposite side of the tube, and afterward turning down in front of the other side of the tube the other portion between the slits, and fastening or sewing it to the next adjacent side of the tube.

2. The method, substantially as described, of making the bottoming of a bag, it consisting in slitting the tubular body at one end, explained, at opposite parts thereof, and next folding at its ends, as described, one of the portions between -the slits, and turning such portion into the tube and fastening or sewing it to the opposite side of the tube, and next folding at its ends, as described, the other por tion between the slits, and turning it down in front of the other side of the bag and fastening it thereto, all being essentially as set forth.

3. As an improved manufacture, a bag as made of a tube slitted at one end, as described, and having one of the parts between the slits roo turned Within the tube and fastened to the 0pposite side thereof, and the other of said parts turned in front of the other side of the tube and fastened thereto, all being substantially 5 as set forth.

4. As an improved manufacture, a bag, as l made of a tube slitted at one end, as described, and having one ot' the parts between the slits folded at its ends and turned Within the tube 1o and fastened to the opposite side thereof', and

the other part between the two slits folded at its ends, as explained, and turned over in front of the other side of the tube and fastened or sewed thereto, al1 being substantially as set forth. f'
